LDR (Light Dependent Resistor) veya foto diren\u00e7, \u00e7evresel \u0131\u015f\u0131k seviyesine duyarl\u0131 olan ve \u0131\u015f\u0131\u011fa kar\u015f\u0131 direncini de\u011fi\u015ftiren bir elektronik bile\u015fendir.<\/p>\n\n\n\n

LDR Foto Diren\u00e7 Mod\u00fcl\u00fc Nedir?<\/strong><\/p>\n\n\n\n

LDR (Light Dependent Resistor) veya foto diren\u00e7, \u0131\u015f\u0131\u011fa kar\u015f\u0131 duyarl\u0131 olan bir diren\u00e7 t\u00fcr\u00fcd\u00fcr. I\u015f\u0131\u011f\u0131n yo\u011funlu\u011fu artt\u0131k\u00e7a, LDR’nin direnci azal\u0131r; tersine, \u0131\u015f\u0131k azald\u0131k\u00e7a diren\u00e7 artar. Bu \u00f6zellik, LDR’yi \u00e7evresel \u0131\u015f\u0131k seviyelerini \u00f6l\u00e7mek veya kontrol etmek i\u00e7in kullan\u0131\u015fl\u0131 bir bile\u015fen yapar.<\/p>\n\n\n\n

LDR foto diren\u00e7 mod\u00fclleri, bu LDR’yi bir mod\u00fcl \u00fczerinde entegre eder ve daha kolay bir \u015fekilde kullan\u0131lmas\u0131n\u0131 sa\u011flar. Genellikle mod\u00fcl, LDR’nin yan\u0131 s\u0131ra bir \u00e7\u0131k\u0131\u015f voltaj\u0131 ve ba\u011flant\u0131 pinleri gibi ek bile\u015fenleri i\u00e7erir. Bu mod\u00fcller, \u0131\u015f\u0131\u011fa duyarl\u0131l\u0131klar\u0131 ve hassasiyetleri farkl\u0131 olan bir\u00e7ok farkl\u0131 \u00e7e\u015fitte mevcuttur.<\/p>\n\n\n\n

\u00c7al\u0131\u015fma Prensibi<\/strong><\/p>\n\n\n\n

LDR foto diren\u00e7 mod\u00fclleri, i\u00e7erdikleri LDR’nin \u0131\u015f\u0131\u011fa kar\u015f\u0131 diren\u00e7 de\u011fi\u015fikli\u011fi \u00f6zelli\u011fini kullan\u0131r. I\u015f\u0131k yo\u011funlu\u011fu artt\u0131k\u00e7a, LDR’nin direnci azal\u0131r ve elektrik ak\u0131m\u0131 daha kolay akar. I\u015f\u0131k azald\u0131k\u00e7a, LDR’nin direnci artar ve elektrik ak\u0131m\u0131 zorla\u015f\u0131r.<\/p>\n\n\n\n

Bu diren\u00e7 de\u011fi\u015fikli\u011fi, LDR foto diren\u00e7 mod\u00fcl\u00fcn\u00fcn \u00e7\u0131k\u0131\u015f voltaj\u0131nda bir de\u011fi\u015fikli\u011fe yol a\u00e7ar. Bu \u00e7\u0131k\u0131\u015f voltaj\u0131, \u0131\u015f\u0131\u011f\u0131n yo\u011funlu\u011funa g\u00f6re de\u011fi\u015fir. Mod\u00fcl\u00fcn \u00e7\u0131k\u0131\u015f\u0131 analog bir sinyal olabilir (\u00f6rne\u011fin, bir voltaj seviyesi) veya dijital bir sinyal olabilir (\u00f6rne\u011fin, y\u00fcksek ve d\u00fc\u015f\u00fck seviyeler aras\u0131nda ge\u00e7i\u015f yapabilir).<\/p>\n\n\n\n
